One of the NFL’s worst run defenses fell a bit further Tuesday without playing a game or having a practice. Vincent Taylor, Miami’s developing second-year defensive tackle who was the leading tackler (27 tackles) and sack producer (2.0) among interior defensive linemen, was put on the injured reserve list because of a foot injury sustained in last week’s loss at Houston. Taylor’s absence cuts into a unit that was already leaking oil midway through the season. Now comes Taylor’s loss.

Set aside the soap opera at quarterback, where Ryan Tannehill, who has been sidelined the last three games with a right shoulder injury, didn’t throw Wednesday during the media-allotted practice watching time. Tannehill’s replacement, Brock Osweiler, has been OK.

The drama at defensive tackle, where newly signed Sylvester Williams and newly signed Ziggy Hood will play, is a bigger problem right now. And unlikely as it seems, this could be the biggest problem of the season.
